b)
c)
d)
e)
f)
Explanation of Solution
a) The structure of the given alkene as the product of
In
Hence, the structure of alkyl bromide is as follows:
b) The structure of the given alkene as the product of
In
So, there are two possible structures of alkyl bromide which are as follows:
The primary alkyl bromide forms the desired product but the tertiary alkyl bromide can form two alkenes with trisubstituted alkene as the major product. The reaction is as follows:
Hence, the structure of the compound that forms the given alkene as an exclusive product of
c)The structure of given alkene as the product of
In
So, there are two possible structures of alkyl bromide as follows:
The alkyl bromide in which
Hence, the structure of the compound that forms the given alkene as an exclusive product of
d) The structure of the given alkene as the product of
In
So, there are two possible structures of alkyl bromide as follows:
The primary alkyl bromide forms the desired product but the secondary alkyl bromide can form two alkenes with trisubstituted alkene as the major product.
Hence, the structure of the compound that forms the given alkene as an exclusive product of
e) The structural formula of the given alkene is shown below:
In
So, there are two possible structures of alkyl bromide as follows:
The alkyl bromide in which
Hence, the structure of the compound that forms the given alkene as an exclusive product of
f) The structural formula of the given alkene is shown below:
In
So, there are two possible structures of alkyl bromide as follows:
The secondary alkyl bromide forms two alkenesbut the tertiary alkyl bromide forms only the desired product as shown in following equations:
